Questa pagina descrive come gestire il numero di tabelle temporanee. Questo
consigliere si chiama Riconfigura le impostazioni delle tabelle temporanee.
Ogni giorno, questo sistema di raccomandazione analizza il numero di tabelle temporanee create sul disco rispetto al numero totale di tabelle temporanee. Se il numero di tabelle temporanee create sul disco è superiore al 20% del numero totale di tabelle, questo sistema di suggerimenti ti consiglia di eseguire una delle seguenti operazioni:
Aumenta il valore del flag tmp_table_size, del flag max_heap_table_size o di entrambi.
Se i valori di max_heap_tmp_table_size e tmp_table_size non sono uguali,
aumenta il valore più piccolo in modo che corrisponda a quello più grande.
Se i valori di max_heap_tmp_table_size e tmp_table_size sono uguali,
aumentali entrambi a un valore maggiore.
Per ulteriori informazioni su come aumentare il valore di tmp_table_size, vedi
tmp_table_size.
